Be it known that I, ENOCH J. BnA'oKMoN,

a citizen'of'the United States, residing at Sherman, in -the county of Grayson and 5'State of Texas, have invented certain new and useful Improvements in Cotton Cleaning and Extracting Machines, of which the following is a specification.

This invention relates to cotton extracting and cleaning machines, and may be use either-in conjunction with a gin to clean hand picked cotton and better'prepare it for the ginning operation, or it may be used for extracting cotton from unripe and closed bolls.- The agencies employed in performing'the functions of the present construction are both mechanical and pneumatic andcar- .ried out by means of a suction fan, whereby the cotton from a wagon or bin enteringl it at the side is carried around within a cy "ndrical chamber formed of inclined staves which 'thresh and separate the cotton from the hulls and pass it throu h the staves to a discharge flue extending rom the bottoin- I a longitud nally disposed inclined screen 16 of the -fan case togin stands.

By the special construction of parts hereinafter "described and claimed, as well as by the general combination, arrangement and cotiperation of the elements entering-into the machine as a whole, I have devised a machine which will operate in a continuous and highly eflicient manner to separate impuri ties from said cotton, or with equal efiiciency to crush bolls, open or clos ed,--a'nd separate .35 the cotton thereof from the hulls.-

,In the accompanying drawings which serve to illustrate this invention more fully, Figure 1, is a sidev elevation, a portion be ng broken away to disclose interior mechanism.

40 Fig. 2 is a plan view partly in section through the line ortions broken away to clearly show more important. interior features.

In the embodiment of the invention shown in the drawings 1 represents a suction fan or blower having a circular opening 2 in the front. side 3, over which opening 1S bolted a plate 4,'provided"' with an opening 5 that is connected through the usual conveyer' trunk (not shown) W1tl1 a telescopic section, said telescopic section being adapted to rest in the bin or wagonfron which the seed cotton is to be elevated. The-fan 1 is equipped with a rotor comprising a perfo- 66 rated disk '6 secured to the edges of fan wings 7, all mounted on a shaft that is Specification of Letters Patent.

supported in the usual bearingsQ, and'ma be driven from any convenient pgint by be t 10. The wings 7 are not as wide as the interior width of the fan casing, so a space 11 6 is formed between the disk 6 and the plate 4 in which the cotton to be cleaned first enters; A-cylindrical wall is formed within the fan casing by alurality of laterally I disposed, inwardly inc ined metal staves 12, 55 spaced apart and secured to the sides of the casing an'v suitable manner, said wall formmg'a cylindrical chamber 13 in which the fan revolves. The perforated 'disk 6 prevents .the cotton entering the fan from 70 passingto the fan wings, hence theair blast carries it to the periphery of the fan which .threshes it around against the inwardly in-' 'clinededges of the staves, thus. removing the'seed cotton from the hulls and blowing it-through between the'adjacent edges of the stavesto-a chamber 14, around which'it travelsto the bottom of the fan where it attains, a horizontal course and. contacts an adjustable deflector 1'5,that directs it against 30 having a mesh suita le only for the passage. of small trash and dust; the cotton passing along beneath the screen, and through a conduit 17 to: the cotton gin. A little in- 35 termixture of bulls, husks and other foreign matter may also be carried with the seed cotton, but will .readilybe separated from the lint by the; ginning process.

All hulls, stems and trashotoo large to pass between the edges of the staves 12, will be threshed around in the chamber 13, and by the constant inlet flow of cotton at the front side,gradually forced to the back side of the fan case, and out through an openin ,5 18, into a conduit 19 that may be extended to a point outside of the gin house. An inwardly curved deflector 20, secured in the chamber 13, also tends to deflect-the hulls in the desired direction. The opening 18 is formed in a metal plate 21, which is curved to conform to the circle formed by the inclined staves 12, and a laterally disposed baflle portion 22 of the plate extends.

seen that I provide a cotton extracting and 11b cleaning machine that is exceedingly simple in construction and efiicient in operation,

and while I. have shown and .described a specific embodiment of means for carrying the principles of my invention into p ractical operation, I desire it to be understood that the s eci-fic formshown, while the best form a in w ich I at present contemplate carrying my invention into practical operation, is merely illustrative 0 an operative embodiment of practical means, and I do not limit flector disposed in the chamber adjacent to the cylindrical wall, a trash conducting conduit, said conduit having communication with the fan. chamber through anopening in the cylindrical wall, as set forth;

2. In a machine of the class described, in

combination with a fan-casing and a fan positioned therein, a circular wall formedof transverse staves dividin the space between an wings and the outer shell of the easing into an inner and i the periphery of the an outer cylindrical chamber, said staves bemg so positioned and disposed as to present one ed e of. each in a osition to form a serrate innersurface o the wall for disintegrating'the cotton burs, a clearance space between the'edges" of the staves to afford an uninterrupted passage from the'saidinner chamber between them, whereby the cotton as extracted from the burs ,may be readily passed by ;.theair-' blast through said spaces to the outer-chamber of the fan, and thence throu h aconduit'le'ading to a cotton gin.

3. a machine of the-class described, in combination with afan casing and a fan positioned therein, a serrated circular wall formed of stavesspaeed apart for the passage of cotton, and-positioned exterior'of the fan, dividing the intervenin space be= tween the fan and the outer s ell of the casin into an inner and an outer cylindrica chamber, an opening throu h the wall into a conduit for-the'passage o hulls and trash from the inner chamber, the outer chamber of the fan conducting and passing the cotton received therein to a conduit having a deflector member disposed and adjacent to' the mouth thereof, causing-the cotton to pass alon beneath an inclined horizontally dispose cotton gin.
